6.11 Analog input module SM 331, AI 6 x TC isolated
(6ES7331-7PE10-0AB0)
Order number
6ES7331-7PE10-0AB0
Properties
The SM 331; AI 6 x TC isolated analog input module has the following properties:
● 6 inputs in one group
● Electrical isolation 250 VAC between channels
● Support for user calibration via SIMATIC PDM
● Compensation via internal or external cold spot comparison, or via remote access by
means of a separate thermoresistor module.
● Measurement type can be set for each channel
– Voltage
– Temperature
● Resolution of 15 bits + sign
● Any measuring range for each channel
● Programmable diagnostics and diagnostic interrupt
● Limit value monitoring can be set for 6 channels
● Programmable hardware interrupt when limit is exceeded
● Electrically isolated from the CPU
Resolution
The maximum resolution of the measured value (15 bits + sign or 0.1 K) is independent of
the programmed integration time.
Diagnostics
For information on diagnostics messages at the "group diagnostics" parameter, refer to
chapter Diagnostic messages of analog input modules (Page 296).
Hardware interrupts
Hardware interrupts can be set in
STEP 7
for all channels.
